We’re excited to launch our new product IoT SIMS – SIM cards designed specifically for IoT devices. IoT SIM cards offer several unique features and benefits for machine‑to‑machine communication, and we’ve created a handy guide covering everything you need to know.
What is an IoT SIM card?
These SIM cards connect IoT devices to any mobile network, enabling them to transmit and receive data over the internet. They provide organisations with uninterrupted connectivity and complete control over their mobile estate. IoT devices can include sensors, meters, trackers, industrial equipment, and more. An IoT SIM card—also known as an M2M (Machine‑to‑Machine) SIM or eSIM—is optimised for machine‑to‑machine communication rather than typical smartphone usage.
What features do they have?
- Private Static / Fixed IP as Standard: Connectivity as a Service (CaaS) provides fixed private IP addressing by default.
- Simple Setup, Single APN and Remote Management: A single Access Point Name (APN) simplifies device connections regardless of the underlying network. Combined with a VPN to your IoT infrastructure, devices can join your private managed network without the need for complex cabling or managing multiple network relationships. Remote management through cloud‑based platforms further streamlines device configuration.
- SIM Form Factor & Activation: Available in a standard SIM form factor—or activated via QR code—for compatibility with a wide range of devices.
- Network Access: All SIMs and devices have access to every UK network with a standard 5G data connection for optimal data transfer rates.
- eSIM Solution: Enables over‑the‑air tariff and network updates so that SIMs can be used globally.
- IP Configuration: Comes with a fixed private IP with the option to overlay a fixed public‑facing IP if needed.
- SIM Management Platform: Provides real‑time visibility of data usage, with tools to set caps and receive alerts.
- Low Power Consumption: Optimised for minimal power usage to extend the battery life of IoT devices.
- Global Connectivity: Many IoT SIMs offer global coverage, crucial for international deployments.
- Security: Built‑in security features, including authentication and encryption, ensure secure communication between devices and the cloud.
- Scalability: Designed to scale and accommodate a large number of devices, suitable for both small‑scale and large‑scale IoT projects.
- Customisation: Tailor solutions to the specific needs of IoT applications, whether it’s low‑data or high‑bandwidth options.
